In this article, we spotlight five legendary esports tournaments where overlooked squads defied astronomical odds, clinched victory, and walked away with millions in prize money. From clutch comebacks to flawless strategies, these moments remind us why esports underdog wins remain some of the most thrilling spectacles in gaming history.

Cloud9’s Miracle Run at ELEAGUE Major: Boston 2018 (CS:GO)

The Counter-Strike: Global Offensive scene was ruled by European powerhouses in 2018, with North American teams like Cloud9 dismissed as perennial underdogs. Heading into the ELEAGUE Major in Boston—the first CS:GO Major hosted in the USA—Cloud9 entered as massive underdogs with odds exceeding 50-1. The roster, featuring tarik, autimatic, Stewie2k, Skadoodle, and RUSH, had struggled for consistency, often exiting early in big events.

Defying expectations, Cloud9 navigated a grueling bracket, upsetting favorites like MIBR and NaVi along the way. The grand final against FaZe Clan epitomized their grit: down 0-2 in maps, they rallied with Skadoodle’s AWP heroics to force overtime, ultimately winning 2-1. This marked the first (and still only) Major victory for a North American team. The total prize pool was $1 million USD, with Cloud9 claiming $500,000—the largest sum ever for an NA squad at the time. Their triumph ignited NA CS:GO hopes, boosted sponsorships, and became a benchmark for underdog resilience, proving roster synergy can topple dynasties.

OG’s Qualifier-to-Champions Journey at The International 2018 (Dota 2)

Dota 2’s The International (TI) is esports’ richest event, and TI8 in Vancouver boasted a staggering $25.5 million prize pool crowdfunded via Battle Pass sales. OG, captained by Johan “N0tail” Sundstein, scraped into the main event through the open qualifiers—a humiliating path for a team with prior TI pedigree. With ana, s4, Topson, and Ceb, they were mocked as a “B-tier” squad amid favorites like PSG.LGD and Evil Geniuses.

OG flipped the script with innovative drafts and ana’s mid-lane dominance. They dismantled heavyweights in the upper bracket, including a 2-0 over PSG.LGD. The grand final against PSG.LGD was a 3-2 marathon, where OG’s resilience shone in game 5’s 70-minute epic. They secured $11.23 million—the single largest payday in esports history at that point. This win validated their high-risk playstyle, launched Topson’s stardom, and set the stage for back-to-back glory. OG’s story underscores how qualifier grit and adaptability can conquer TI’s chaos.

Alliance’s Open Qualifier Shock at The International 2013 (Dota 2)

In Dota 2’s early pro era, TI3 in BenQ Seattle featured a $2.87 million pool, dwarfing traditional sports purses. Alliance, a Swedish squad led by Jonathan “Loda” Berg, entered via open qualifiers—no invites, no hype. With AdmiralBulldog, s4, EGM, and Akke, they were unknowns facing juggernauts like NaVi and Orange.

Their run was pure magic: flawless group stages, upsets over DK and NaVi in playoffs. The upper bracket final saw them crush NaVi 2-0, but a lower bracket scare against Orange tested their mettle. In the grand final, Alliance dominated NaVi 3-0 with superior teamfights and Loda’s Puppey-like vision control. They pocketed $1.28 million—nearly half the pool—and catapulted Dota into mainstream awareness. This victory birthed legends like s4 (future TI winner) and proved open qualifiers could yield champions, influencing Valve’s tournament structure for years.

Tundra Esports’ Dominant Surprise at The International 2022 (Dota 2)

TI11 (held in Singapore due to logistics) shattered records with a $40 million pool, the fattest ever. Tundra Esports, a relatively new org with a mixed roster—Nine, Topson (ex-OG), Saksa, bzm, and 33—qualified solidly but ranked mid-tier behind beasts like Team Secret and Gaimin Gladiators.

Tundra’s campaign was surgical: undefeated upper bracket run, crushing TSpirit 2-0 in the final after a 2-1 vs. Secret. Topson’s Io-Spectre combo and Nine’s offlane mastery overwhelmed foes. They swept the grand final 3-0, claiming $18.4 million—a record team haul. As massive 10-1 underdogs pre-tournament, their macro perfection and zero map losses in playoffs stunned analysts. Tundra’s win revitalized EU Dota, rewarded Topson’s homecoming, and highlighted how fresh talent disrupts entrenched metas in massive prize environments.

OG’s Repeat Redemption at The International 2019 (Dota 2)

Chasing history at TI9 in Shanghai, OG returned as defending champs but as decided underdogs with a revamped lineup amid roster drama. The $33 million pool amplified stakes, with Chinese teams like PSG.LGD favored after domestic dominance. OG’s core—N0tail, Ceb, ana—plus Topson and s4 battled skepticism post-TI8 fatigue.

They grinded through groups, upsetting Liquid and Alliance en route to finals. A pivotal upper final vs. Dendi’s NaVi showcased ana’s godlike Invoker. Facing Liquid in the 3-1 grand final win, OG’s draft flexibility—featuring insane Timber chainsaws and Void chronospheres—sealed $15.56 million. Back-to-back TI titles (unprecedented) cemented their dynasty status, with N0tail’s leadership iconic. This underdog repeat, against 8-1 odds, proved mental fortitude wins wars, influencing coaching emphases in modern Dota.

These esports underdog triumphs—Cloud9’s NA breakthrough, Alliance’s qualifier fairy tale, OG’s twin TI conquests, and Tundra’s flawless sweep—not only distributed over $47 million collectively but reshaped competitive narratives. They fuel fan passion, boost emerging regions, and remind pros that glory favors the bold. As prize pools swell, expect more shocks. Stay tuned for the next world-shaking upset in esports tournaments!
